Hi,
I am writing a piece of code that checks for zero columns in a matrix. It stores all zero columns it finds in the value col. I later want to check the values for variable col in different if statements. However, when I write it like this it runs into errors:
%find all columns where there is zero vector
col = find(all(R == 0))
if col == [1 2 3]
//does something
end
This code works fine when col has 3 values, but when it has 4 values like col = 1 2 3 4, it gives the error: Matrix dimensions must agree. Is there another way I could check for multiple col values? Thanks!!

you have to be more specific, what is the 'something' that you are doing?

You should just be able to index your if condition.
if col(1:3) == [1 2 3]
// do something
end
